We will tell you if crawl Space Vapor Barrier Installation is not what your Simpsonville crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on piedmont and upstate ground
On clay the ground under a Simpsonville house holds water long after rain, so the barrier is doing two jobs — stopping soil moisture coming up, and keeping the space off ground that stays wet for days at a time.
Around Simpsonville the damage tends to accumulate in steps, a little with each storm, rather than arriving all at once. By the time it is noticed upstairs it has usually been building for a while.

Vapor barrier in Simpsonville: common questions
There is already plastic under my Simpsonville house. Is that enough?
Often not. Most of what we find has been laid loose, has torn, or was never sealed at the seams and walls. Unsealed sheeting performs much closer to bare soil than to a finished barrier.
Barrier or full encapsulation for a Simpsonville home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Greenville County property needs should follow a humidity reading, not a preference.
What should I have ready when I call about my Simpsonville home?
Your street in Simpsonville, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
Do you cover all of Simpsonville?
Yes — Simpsonville and the surrounding part of Greenville County, including the 29680 area. We also work in nearby Mauldin, Fountain Inn and Conestee.
Is the damage sudden or gradual here?
Gradual, mostly. Around Simpsonville it arrives in steps — a little with each storm — so by the time a floor feels soft upstairs the framing has usually been damp for a while.
I already have plastic down there. Is that enough?
Often not. Most of the sheeting we find has been laid loose, has torn, has pulled away from the walls or was never sealed at the seams. Unsealed, incomplete sheeting lets ground moisture track around and through it, and performs much closer to bare soil than to a finished barrier.
